Stand up straight holding on to a supportive surface.
Place a resistance band around the ankle on your affected leg.
Stand firmly on the other end of the resistance band.
Keeping your legs straight, slowly take your affected leg out to the side against the resistance of the band.
Do not allow your body to lean or your pelvis to twist.
Control the movement as you lower your leg back down to the starting position.
As an alternative, you can anchor the resistance band to a sturdy object.
